*wrād-

1590s, "to pluck up by the roots," from French déraciner, from Old French desraciner "uproot, dig out, pull up by the roots," from des- (see dis-) + racine "root," from Late Latin radicina, diminutive of Latin radix "root" (from PIE root *wrād- "branch, root"). Related: Deracinated.

The French past participle, déraciné, literally "uprooted," was used in English from 1921 in a sense of "uprooted from one's national or social environment."

early 15c., "destroy utterly," literally "pull up by the roots," from Latin eradicatus, past participle of eradicare "root out, extirpate, annihilate," from assimilated form of ex "out" (see ex-) + radix (genitive radicis) "root" (from PIE root *wrād- "branch, root"). Related: Eradicated; eradicating; eradicable. The native form of the same idea is in Middle English outrōten "to root (something) out, eradicate" (early 15c.).
